Bottom line: The honest split is battery life. The Apple Watch Series 12 at $389.99 is the better computer on your wrist and needs charging daily. The Garmin Forerunner 165 at $191.10 is the better training device and runs about eleven days. If you want one device for notifications, payments and apps, buy Apple and accept the nightly charge. If you want training data and sleep tracking without thinking about the charger, buy Garmin and save $200. Prices checked 9 November 2026.

Battery Is the Decision, Not the Specs
Most comparisons here list sensors and screens. Those are close enough not to matter. The charging interval is what actually changes how you use the device.
A watch charged every night is not on your wrist at night, which means no sleep tracking, no overnight heart rate variability and no morning readiness score unless you build a charging routine around a different part of the day. Plenty of Apple Watch owners do exactly that, charging while showering or at a desk. It works, and it is a habit you have to maintain.
A watch that lasts eleven days gets charged when you notice, and it is on your wrist every night by default. That is why the recovery features on a Garmin tend to produce complete data and the equivalent features on an Apple Watch often do not, for reasons that have nothing to do with sensor quality.
So the question is not which has better hardware. It is whether you will keep up a charging routine, which is a question about you rather than the watch.
The Numbers
| Apple Watch S12 | Forerunner 165 | |
|---|---|---|
| Price | $389.99 | $191.10 |
| Battery, daily use | About a day | Up to 11 days |
| Built-in GPS | Yes | Yes |
| Training platform | Apple Fitness | Garmin Connect, free |
| Apps, payments, calls | Full | Limited |
| Requires iPhone | Yes | No |
The last row rules out the Apple Watch entirely for Android users, which is worth stating before anything else. Garmin works with both.
The price row is the other blunt one. At $389.99 against $191.10, the Apple Watch costs roughly double, and the gap buys you a smartwatch rather than a better training device. Even the Forerunner 265 at $440 is in the same bracket as the Apple Watch while doing considerably more for running.
Where Garmin Is Genuinely Better for Training
Three things, and they are the reasons serious runners and cyclists tend to end up on Garmin regardless of which phone they carry.
Structured training. Garmin Coach builds adaptive plans, daily suggested workouts respond to recent training, and the watch guides you through intervals on the wrist. Apple’s equivalent is thinner and leans on third-party apps that drain the battery further.
Recovery metrics, free and complete. HRV status, Body Battery and training readiness come with the watch at no subscription cost, and because you wear it overnight they actually populate. We went through the same point in our Oura versus Garmin comparison.
The integration web. Garmin Connect talks to nearly everything in endurance sport, from bike computers to coaching platforms to Strava. If your coach writes plans somewhere, it probably supports Garmin.
None of that makes Apple a bad watch. It makes it a general-purpose device competing against a specialist, and our sub-$200 guide and COROS comparison cover the specialist end.
Where Apple Is Genuinely Better
Worth being even-handed, because the Apple Watch wins decisively on things that matter to most people more than interval guidance does.
It is a better everyday device. Notifications, replies, payments, calls, unlocking things, a vastly better app ecosystem. If you want one object on your wrist that does everything, the Series 12 is not close to a Garmin, it is simply ahead.
Safety features. Fall detection, crash detection and emergency calling are mature and well implemented, and for some buyers that single category settles the decision regardless of training.
Casual fitness is well served. If your training is classes, walks, gym sessions and the occasional run, Apple’s activity rings and Fitness app are more motivating for more people than Garmin’s data-dense screens. Our Apple Watch versus Fitbit comparison covers that end of the market.
The pattern across all three: Apple is better at being a watch, Garmin is better at being a training tool. Both do the other job adequately and neither does it excellently.

What Neither One Fixes
Before spending either amount, it is worth knowing what the ceiling is, because both sit under the same one.
Both read heart rate optically at the wrist, and both degrade in the same situation: higher intensity, with the sensor shifting against moving skin and tendons sliding underneath. The common failure is cadence lock, where the watch reports your step rate as your pulse with complete confidence. That is a wrist-location problem, not a price or brand problem.
Sleep is similar. Validation research consistently finds consumer wearables detect sleep versus wake well, above 95 percent sensitivity, while agreement on individual sleep stages is considerably weaker, with devices systematically over-labelling sleep. Our guide to the research goes study by study.
If accurate heart rate during hard efforts is your actual goal, a chest strap at around $100 does more than the $200 difference between these two watches. It pairs with either one, and our heart rate monitor roundup covers it.
The Both-Watches Answer
A sizeable number of people end up owning both, and it is worth saying why rather than pretending it is irrational.
The usual pattern is an Apple Watch for daily wear and a Garmin for training and sleep. It works, and it costs $580 at today’s prices, which is a lot for overlapping step counts. Before going there, be clear which device you would actually reach for on a Tuesday, because most people discover within a month that one of them lives in a drawer.
A cheaper version of the same idea: keep whichever watch you own, and add a chest strap for accurate training data. That covers the real gap for about $100 instead of $200 to $390, and it is the recommendation we keep arriving at across this category.
If you are buying one device and genuinely torn, the tiebreaker is the phone in your pocket. Apple Watch requires an iPhone. Garmin does not care.
How We Evaluate
We do not train with either device and we will not imply we do. Prices come from the sellers’ own Amazon listings, checked by direct navigation on 9 November 2026: Apple Watch Series 12 GPS 42mm at $389.99, Garmin Forerunner 165 at $191.10 and Forerunner 265 at $440.00. Battery figures and feature descriptions come from each manufacturer’s published specifications, including Garmin’s stated eleven-day smartwatch-mode battery and the absence of any subscription for HRV status, Body Battery and training readiness. Accuracy statements come from published validation research on consumer wearables, cited in the linked guide. Recommendations are editorial judgment, labelled as such, and both brands discount, which our Apple Watch discount history and three-year cost breakdown cover.
The Short Version
Android user: Garmin. The Apple Watch requires an iPhone, so the comparison ends there.
You train seriously: Garmin. Structured plans, free recovery metrics, and a battery that means you actually wear it to bed. $191.10 against $389.99.
You want one device for everything: Apple Watch. It is a far better everyday computer and the fitness side is adequate for most people.
You will not charge a watch daily: Garmin. This is the most common reason Apple Watch recovery data ends up incomplete.
You want better data, not a new watch: keep what you own and buy a chest strap. Roughly $100 and it fixes the limitation both devices share.

FAQ
Is Garmin better than Apple Watch for running?
Yes, meaningfully. Garmin Coach builds adaptive plans, daily suggested workouts respond to recent training, and the integration with endurance platforms is far deeper. The Apple Watch records runs competently but is a general-purpose device.
Can you use an Apple Watch with Android?
No. It requires an iPhone. Garmin works with both, which settles the decision for Android users before any other consideration.
How long does each battery last?
The Apple Watch is about a day in normal use. The Forerunner 165 is rated up to eleven days in smartwatch mode. That gap is why Garmin sleep and recovery data tends to be complete and Apple’s often is not.
Does Garmin charge a subscription for recovery features?
No. HRV status, Body Battery, sleep staging and training readiness are included permanently with the watch.
Which is more accurate for heart rate?
Neither has an edge that matters. Both read optically at the wrist and both degrade at higher intensity as the sensor shifts. A chest strap fixes that for either device for around $100.
